my young female guppy cant swim straight-by this i mean she looks although she has got a weight attached to her tail and her tail is to heavy for her body.no other symptoms,no purtruding scales spots or ragged fins she otherwise looks really healthy! she does on occasion swim around but this is a great effort for her.
